Québec Cannabis Survey 2023

In 2023, nearly 17% of Quebecers aged 15 and over had used cannabis in the past 12 months. This proportion was 19% in 2022. A decrease was also observed between 2022 and 2023 among those aged 15 to 20 (25% vs. 23%) and those aged 35 and over (14% vs. 12%).

The Québec Cannabis Survey (QCS) was carried out between February and July 2023 among 13,209 people. It aims to measure changes in cannabis use in Québec. In addition to monitoring emerging phenomena, it examines cannabis use and associated behaviours as well as perceptions towards cannabis. Various indicators are covered by the survey, including methods of use, reasons for using, context of use, sources of supply, risk of problematic use, social norms, and perceptions towards cannabis.
